BATTERY COVER AND ELEMENT SUPPORT.

Specification of Letters Patent.

Patented May '5, 1908.

Application riled May 29, 1905. Serial No. 262,952.

T 0 all whom it may concern:

Be it known that I, CHARLES B. SOHOEN- MEIIL, a citizen of the United States, and resident of Waterbury, in the county of New Haven and State of Connecticut, have invented. certain new and useful- Improvements in Battery Covers and Element Supports, of which the following is a specification.

This invention relates to new and useful improvements in battery bridges or covers, designed to support both the positive and negative element ofa battery. 7

In practice I have found that in some forms of batteries containing an oil covered solution, a metallic de osit will formon the surface of the oil, Wit the working of the battery and the decomposition of the ele-' ments, and that such metallic coveringis frequently sufficient to form aconductor intermediate of the elements, and to short circuit the battery. I also find that it is particularly desirable to provide a support for the central or negative element that will rig idly retain the same positively in the middle of the zinc, so as to prevent them contacting or decomposing unevenly. The purpose of my invention therefore, is to rovide a cover or bridge which can prefera ly be madeof porcelain, and have an in; tegra extensionformedthereon'for the at, tachment of one of the battery elements,- Which extension will be ,sufficientl .long to retain its element below the norma solution line of the-battery; t'oconstruet the e'xten' sion of a material and in a manner to protect the supporting rod of the eienient from attack byr-the surface sediment that may form.

on top of the solution, contained Within the jar and to provide an extension which in deg sign shall be proper to form a -firm engagement'for the element and its supporting rod so as to insure a rigid connection-of the two. Upon the accompanying drawings forming a art of this specification similar letters of re erence denote like or corresponding parts throughout-the several figures and of which,

' Figure 1, shows an invertedpian View of a battery cover including my improved insulating extension. Fig. 2; shows a central vertical cross section through the cover. shown in Fig. l,- and illustrating by, full lines" a compressed copper oxid element attached,

and by dotted lines, a cylindrical zinc, and

Fig. 3 shows a sideelevation of the coverillustrated in the preceding figures Fig. 4, is a further vertical cross section through a cover containing an extension having two holes therethrough for the attachment of an element .Referring in detail to the characters of reference marked upon the drawings a represents a jar shown in dotted lines, and b the top or surface line of solution therein.

8. indicates a cover whichm'ay beof any preferred general' design and likewise of any suitable insulating material, as for instance porcelain. This cover may contain a shouldered ledge for the engagement of the top of a battery jar, and further 'is provided with holes d for thereception of the supporting" rods e-e of the positive or zinc element shown indottedlines.

The I epending insulating extension of the. cover, for the. negative element It is formed integral and of the same material as the cover, and. .is situated central of the U underside'of the cover an'd'is referably of a tapering cylindrical or oblong orm, with one -or more holes'i therethrou hand a shouldered recess j'at the lower end 0 'saidholeor holes.

These holes extend through both' the extension and cover, and serve toreceive the attachin'g or. supporting rod not the negative element h, while the shouldered enlargement 1 serves to receive'the nut 70 that clamps the v compressed oxid of copper element to its supporting rod. This nut when seated "in therecess serves to hold the rod and-element againstturning when the wing" and binding nutsl and ht "are being attached.

L .As clearly shown in Fi 2-, the depending projection g, extends wel belowthe surface ne' 1); of the solution and constitutes a pro- '-tecting-lug for the attaching rod or support- "ing' member a, of the element h, while its extended annular lowersurfacecovers the top of the element.-

' -The form of cover shown in Fig. 4, is providedwith two holes i which are arranged to pass through both the cover and'extensionv and is designed to accommodate a slightly different style ofelement and support. This cover also contains a lug 0 on the top havingv atransverse'hole p therethro'ugh for-the securement of the element rod.

Having thus described my invention, what I claim and desire to secure by. Letters Patent l. A. battery bridge, and a supporting 3 seep es or more holes through both said extension anccli cover to receive the element supporting :00 s." i

4. A battery bridge or cover having an integral extension to cover the supporting 20 rod and end of a battery element, and a shouldered pocket in said extension to hold. the element and rod from turning.
